Abstract
The utility model discloses a backward flow mixing screw which comprises a screw body; a main thread is arranged on the screw body; a plurality of mixed threads are arranged on the screw body in parallel; the screw edge heights of the mixing threads are smaller than the screw edge height of the main thread; the utility model employs a reversely mixing principle and improves melting and color mixing based on material mixing, thereby having smaller shearing on the materials, being able to be applied to a plurality of materials, being able to be used on a plurality of materials sensitive to shearing and heat, and having good commonality.
Description
Technical field
The utility model relates to a kind of feeding spiro rod of injection machine rubber melting cylinder, particularly a kind of injection machine rubber melting cylinder feeding spiro rod with many blended thread.
Background technology
The material fusion of injection machine realizes by the rubber melting cylinder assembly.By being installed in rubber melting cylinder assembly inner screw material is fed forward, utilizes electro-heat equipment again the material fusion.In conventional screw design, exist fusion speed slow always, temperature fluctuation is big, plastify inhomogeneous, shortcoming such as mixed effect is bad.For solving this type of problem, existing injection machine generally adopts mixing screw to come feeding, but general mixing screw mainly is the purpose that reaches colour mixture, acceleration fusion by strong shearing, but the strong screw rod of this shearing causes the decomposition of material easily, and versatility is bad.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the anti-stream mixing screw that a kind of shearing to material is less, can not cause the material decomposition.
The technical scheme that its technical problem that solves the utility model adopts is:
Anti-stream mixing screw comprises the body of rod, and the body of rod is provided with main thread, it is characterized in that also being set side by side with some blended thread on the body of rod, and the spiro edge height of blended thread is less than the spiro edge height of main thread.
As the utility model improvement of the technical scheme, main thread and blended thread are provided with some wedged holes.
As the utility model preferred embodiment, described blended thread is provided with three.
The beneficial effects of the utility model are: the utility model adopts the principle of oppositely mixing, improve fusion and colour mixture based on mixing of materials, therefore less to the shearing of material, can be adapted to a lot of materials, some all can use shearing and heat sensitive material, and versatility is good; Screw rod in use, because the gap of main thread and rubber melting cylinder is less, and the spiro edge height of blended thread is less than the spiro edge height of main thread, therefore blended thread and rubber melting cylinder have bigger gap, material can cross that blended thread is counter to be flowed back to, thereby can improve the mixed effect of material, and the propelling flank profil of additional mixing screw thread is an oblique bending, out-of-date when material flow, can produce good drawing effect; Simultaneously because the gap of main thread and rubber melting cylinder is less, thereby can guarantee the self-cleaning function and the mass transport function of screw rod, material is fed forward smoothly; Because main thread and blended thread are provided with some wedged holes, these wedged holes have good stretch function to material, can improve mixed effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the part sectioned view under the utility model user mode;
Fig. 3 is the enlarged diagram at E place among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, anti-stream mixing screw of the present utility model, comprise the body of rod 1, the body of rod 1 is provided with main thread 2, on the body of rod 1, also be set side by side with three blended thread 3,4,5, article three, the spiro edge height of blended thread is less than the spiro edge height of main thread, therefore mixing screw in use, the gap of main thread and rubber melting cylinder 7 is less, and because the spiro edge height of blended thread is less than the spiro edge height of main thread, therefore blended thread and rubber melting cylinder have bigger gap, material can cross that blended thread is counter to be flowed back to like this, thereby can improve the mixed effect of material, simultaneously because the gap of main thread and rubber melting cylinder is less, thereby can guarantee the self-cleaning function and the mass transport function of screw rod material to be fed forward smoothly.The propelling flank profil of main thread is an oblique bending, and is out-of-date when material flow, can produce good drawing effect.
The mixing of materials that is based on the utility model improves fusion and colour mixture, and is therefore less to the shearing of material, can be adapted to a lot of materials, and some all can use shearing and heat sensitive material, and versatility is good.
The above only is preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model can also have other structural change; quantity as blended thread can be made as two or more according to difference and other situation of material; so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
Claims (3)
1. the anti-mixing screw that flows comprises the body of rod, and the body of rod is provided with main thread, it is characterized in that also being set side by side with some blended thread on the body of rod, and the spiro edge height of blended thread is less than the spiro edge height of main thread.
2. anti-stream mixing screw according to claim 1 is characterized in that main thread and blended thread are provided with some wedged holes.
3. anti-stream mixing screw according to claim 1 is characterized in that described blended thread is provided with three.
